The catalytic hydrogenation of D-glucose over a 3 wt% Ru/C catalyst was studied varying the operating conditions in mild conditions range to optimize the obtention of D-sorbitol. The stirring speed, temperature, pressure, and initial glucose concentration were varied between 250 - 700 rpm, 343 - 383 K, 0.5 - 2 mPa, and 0.033 - 0.133 m, respectively. To verify the absence of mass transport limitations, the diffusion of reagents in the gas-liquid interface, the liquid-solid interface, and the internal diffusion in the particles were evaluated. Under the operating conditions studied, the reaction rate showed an order with respect to H2 of 0.586 and with respect to glucose of 0.406. The kinetic data were adjusted using 3 general models and 19 different sub-models based on langmuir-Hinshelwood-Hougen-Watson (lHHW) kinetics. model 3a was the best one interpreting the aqueous phase hydrogenation of glucose (both reagents competitively adsorbed on the catalyst). The H2 adsorption is dissociative and the rate-limiting step is the surface chemical reaction.

本文报道了在过氧化氢存在的情况下,利用过氧化物酶测定水果和蔬菜维生素C的一种新酶法。这种方法以1,4—二氨基苯(加入的合成底物)氧化作用产生的深色产物作为维生素C氧化作用终点进行比色测定。未发现水果和蔬菜含有的其他生物化合物的干扰。这种方法与用抗坏血酸氧化酶的传统方法一样准确快速,但有其另外的优点,使用非常便宜的酶和不需要昂贵的测试设备。

The structural dynamics and flexibility of cell membranes play fundamental roles in the functions of the cells, i.e., signaling, energy transduction, and physiological adaptation. The cyanobacterial thylakoid membrane represents a model membrane that can conduct both oxygenic photosynthesis and respiration simultaneously. In this study, we conducted direct visualization of the global organization and mobility of photosynthetic complexes in thylakoid membranes from a model cyanobacterium, Synechococcus elongatus PCC 7942, using high-resolution atomic force, confocal, and total internal reflection fluorescence microscopy. We visualized the native arrangement and dense packing of photosystem I （PSI）, photosystem II （PSlI）, and cytochrome （Cyt） befwithin thylakoid membranes at the molecular level. Furthermore, we func- tionally tagged PSI, PSlI, Cyt bef, and ATP synthase individually with fluorescent proteins, and revealed the heterogeneous distribution of these four photosynthetic complexes and determined their dynamic features within the crowding membrane environment using live-cell fluorescence imaging. We characterized red light-induced clustering localization and adjustable diffusion of photosynthetic complexes in thylakoid membranes, representative of the reorganization of photosynthetic apparatus in response to environmental changes. Understanding the organization and dynamics of photosynthetic membranes is essential for rational design and construction of artificial photosynthetic systems to undarpin bioenergy development. Knowledge of cyanobacterial thylakoid membranes could also be extended to other cell membranes, such as chloroplast and mitochondrial membranes.

PURPOSE: To investigate the clinical features,visual function outcomes, and adverse events in patients with diffuse unilateral subacute neuroretinitis (DUSN) treated with high-dose oral albendazole. DESIGN: Interventional case series. mETHODS: Twelve Brazilian patients, aged 7 through 36 years, with active DUSN in the early or late clinical stage, were recruited for this study between 1999 and 2001. A small variantmotile worm was found in 4 (33.3% ) of these cases. All patients were treated exclusively with high-dose oral albendazole (400 mg/d) for 30 days. RESUlTS: Improvement of visual acuity, visual field, and active ocular in flammatory signs was observed in all patients after 4 weeks of treatment (median follow-up: 3 years). Also, during the first weeks of treatment, evidence of worm inactivation was documented for the four patients with visible *** adverse drug side effects were observed in any of our cases during follow-up. CONClUSION: High-dose oral albendazole seems to be safe and beneficial for patients with DUSN.
